WHAT IS HEPATITIS C? A viral, blood-borne illness most efficiently transmitted through contact with infected blood. It is potentially fatal. It is most commonly transmitted through needle-sharing by users of injectable drugs. It is occasionally spread sexually or through sharing personal items contaminated with infected blood (e.g. toothbrush). There currently is no vaccine for Hepatitis C.

A small percentage of those who become infected with the disease are able to "clear" the infection.

Most (85 %) develop chronic Hepatitis C. It can lead to chronic liver disease. There currently is no vaccine for Hepatitis C.
